Abstract

The roles of miRNAs in the development of cancer have made them promising tools for novel therapeutic approaches. However, the successful delivery of miRNAs to cancer cells has been hampered by difficulties in developing an effective and sustainable delivery mechanism. Exosomes are small endogenous membrane vesicles that mediate communication between cells by delivering genetic materials. Thus, given their intrinsic properties, exosomes have been a focus for use as biological delivery vehicles for miRNAs transfer. Whether exosomes can effectively deliver exogenous miRNAs to pancreatic ductal adenocarcinoma (PDAC) cells has not been thoroughly investigated. Here, we used exosomes from human umbilical cord mesenchymal stromal cells (hucMSCs) to deliver exogenous miR-145-5p, which inhibited PDAC cell proliferation and invasion and increased apoptosis and cell cycle arrest, concomitant with decreased Smad3 expression in vitro. Using a mouse model, we also demonstrated that overexpressing miR-145-5p significantly reduced the growth of xenograft tumors in vivo. Our findings provide novel insights that exosomes might be an attractive therapeutic vehicle for the clinical administration of miRNAs in patients with PDAC.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
